摘要：
A spectral modulation sensor includes an optically resonant structure comprising a body having a cavity (106) containing a sensitive medium (110) which changes in volume in response to a chemical species. The cavity and the medium include first and second reflective surfaces (107,112) which are relatively displaced with changes in volume of the chemical species. The structure spectrally modulates an input measuring light to produce output light, which is spectrally modulated as a function of the sensed chemical species.
